TripoSR — CoreML (MLProgram fp16) for the AML TouchDesigner family
CoreML conversion of stabilityai/TripoSR (Tochilkin et al., Stability AI + Tripo AI, MIT) for the Geo Gen operator in AML — Apple ML operators for TouchDesigner. Single image → 3D mesh on the Apple Neural Engine in ~2 s on an M-series Air.
